New diesel engines cost up to $20,000 each, so it only makes sense to take care of yours. Oil analysis can identify insidious problems that, if left too long, could drastically shorten your engine's life.

If we had to pick the most frequent cause of diesel engine failure, we would choose antifreeze, the killer extraordinaire. There are several ways coolant can get into the oil — head seals, pin holes in wet liners, injector cups on some types of engines, and the oil cooler. By the time you see discolored oil, the problem has very likely progressed beyond a point of economical repair.

Fuel dilution problems run a close second. Bad injectors and fuel pumps can dump serious levels of fuel into the oil sump, affecting the oil's ability to function properly. Left undetected, a fuel system problem can cause catastrophic engine failure.

These are just a few of the problems faced by diesel engine owners. Preventive maintenance can help you avoid costly repairs. Send us a sample of your used oil for an in-depth look at your diesel engine.

Are you changing your oil often enough? Too often? Is that synthetic oil really worth it? A decade ago, the commercial multi-weight oils on the market were similar. We didn't see much difference in the various brands, and the only real choice for consumers was the grade. Then synthetics were introduced, as were many types of oil additives. Suddenly the question of what to put into your engine became more complicated...

Motorcycle
Oil analysis has long been a common practice among car and truck owners who want to take the best possible care of their vehicles. But lately, an increasing number of people have been analyzing other types of engines too, especially motorcycles.

And why not? If you own a motorcycle, you want to keep it running as long as possible, and oil analysis is a terrific tool for doing so. We have seen samples from most of the motorcycles out there, and chances are good...

Industrial
Industrial groups have traditionally changed oil on an elapsed time basis. This can result in dumping millions of gallons of good oil annually, while doing little to prevent oil-related problems such as "leakers" - machines that leak oil from various seals, costing millions in new oil purchases and downtime. Quarterly oil analysis can eliminate leakers and other oil-related problems, with the added benefits of saving money in unnecessary oil purchases and the cost of getting rid of waste oil...

When a gasoline or diesel engine develops an unexpected problem, it leaves the owner stranded at the side of the road. When an aircraft engine develops an unexpected problem, it can have far more serious consequences.

Oil analysis is a critical component of aircraft maintenance. It's just one tool in your bag of tricks to keep your engine running in top shape. Air-cooled aircraft engines are twitchy, heat-sensitive machines that vary widely in wear...

Sea-going engines require special attention in oil analysis. These engines are not often mechanically different from their land-borne cousins, but they are quite different in their environment and how they are operated. They tend to pull heavy and constant power for long periods of time. The operating environment has the engines situated in holds with little air for cooling and little room for maintenance. Some are treated to splashing bilge water and use seawater for cooling...
